Research Interests

Organometallic chemistry; Transition metal hydrides; Homogeneous catalysis; New ligand environments; Nonclassical bonding.

The main aim of our research programme is to develop new efficient metal catalysts for chemo-, regio-, and enantioselective transformation of organic substrates into value-added products.

We investigate new catalytic methods for reduction of challenging substrates, such as nitriles, amides, esters, and heteroaromatics (pyridines, quinolines etc) and try to make these transformations chemoselectively. We also carry out detailed mechanistic studies, trying to understand the action of our catalysts in order to make even better tailor-made systems with predictable properties.

Our research touches many synthetic, structural and theoretical aspects of transition metal complexes, including inter alia the design of new ligand environments, NMR spectroscopy, X-ray and neutron diffraction analyses, and the bond theory.
